CYLINDER-ADJUSTING DEVICE.

Application filed .Tune 19,

To all whom t hwy concern.'

Be it known that I, ABRAHAM Nevron, a citizen of the United States, and a resident of New York, borough of Brooklyn, in the county of Kingsand State of New York, have invented certain new and useful Improvements in Cylinder-Adjusting Devices, of which the following is a specification.

This invention relates to cylinder adjusting devices and has for its object to provide a device of the class specified, simple inconstruction and efficient and accurate in operation. More particularly my improvements are directed to hand operated means, normally out ofv operative engagement with the cylinder, for relatively adjusting circumferentially, two or more elements of said cylinder.

This device is particularly applicable and useful in connection with envelope machines and I have chosen to illustrate the preferred embodiment of my improvements as applied to the relative adjustment of a creaser and a` glimmer on an envelope machine cylinder.

n the drawing accompanying this specificationz- Figure 1 is a sectional front elevation of so much of an envelope machine as will sufiice to illustrate my improvements. Fig. 2 is a fragmentary sectional end elevation correspondlng with a portion ofwhat is shownin Fig. 1, the section being taken on line 2, 2 of Fig. l. Fig. 3 is a fragmentary sectional end elevation on line 3, 3 of Fig. 1. All the figures of the drawing are to one scale.

Cylinder 4 and gear 8 are fixed to shaft 6 having a bearing in frame 7. Said gear 8 meshes with gear 9 clamped onto the outwardly extending hub of cylinder 5, rotatively adjustable on shaft 10, mounted for rotation in frame 7 By means of said gears, cylinders 4 and 5 are caused to rotate in rolling engagement. Gear 9 is adjustably fixed to shaft 10 by means of disc 11 which is fixed to said shaft by pin 12. Said disc is adjustably fixed to said gear by clamp. screw 13, penetrating slot 14 in said' disc and' threaded into gear 9.

Cylinder 5 is provided with creasing blade 15 located in a peripheral aperture in said cylinder and fastened to the end of wall 16 of said aperture. Protruding through another peripheral aperture in said cylinder and fixed to cylinder shaft 1,0 is glimmer 17 1920. Serial No. 390,293.

Outstanding from one face of gear 9 is bevel gear 19 whose teeth are adapted for meshing with the teeth of bevel pinion 20. Said pinion 20 is fixed to the inner end of shaft 21 and said shaft is mounted for both rotation and endwise movement in bearing 22 of frame 7. The outer end of said shaft 2l has fixed thereto hand wheel 23 and about shaft 21, between the hub of said hand wheel 23 and bearing 22, is push spring 24 normally eflicient for holding pinion 20 from engagement with bevel gear 19. e

For operating the adjusting device, which is accomplished when the machine is not running, Screw 13 is slacked, pinion 2O is pushed into engagement with bevel gear 19 against the resistance of spring 24, and by means of hand wheel 23 said pinion is turned one way or the other as desired, thereby turning gear 19 and gear 9 to which it is fixed and thence cylinder 5, and bearing creaser 15, and' which creaser is thereby moved circumferentially relatively to gummer 17 fixed to shaft 10 and which shaft remains at rest during said adjustment. Screw 13 is then tightened and the adjustment is accomplished. Upon releasing hand Wheel 23, spring 24 forces pinion 20 out of engagement with bevel gear 19 and the adjusted mechanism is ready to run.

This adjustment. or relative settability between the creaser and gumnier is efficient for changing the machine to accommodate different sized envelopes as indicated by different lengths of aps having differlng distances from creasing line to the area to be gummed. It is also efficient for making minor adjustments to compensate for variation in blank feed or for variation due to other causes.

By the term cylinder elements, as herein used, will be understood a plurality of coaxially mounted means adapted to be rotated into successive operative positions, respectively, relatively to a coacting bed and which bed may be cylindrical as illustrated.

I claim:

1. The combination of two cylinder elements, and adjusting means movable transversely the axis of said elements andl norcylinder element -loosel mally disengaged from one of said elements and adapted to 'engage therewith" for adjusting said element relatively to the other element.

2. In an adjust-ingdevice for cylinder elements the combination of a rotatable shaft, a cylinder element fixed thereto, a second cylinder element adjustably fixed thereto, and adjusting means normally disengaged from said second cylinder element and adapted to engage therewith for rotatively adjusting said second element relatively to said first element.

' 3. In an adjustin device for cylinder elements the combination of a rotatable shaft, a cylinder element fixed thereto, a second mounted on said shaft, means for clamping said second element to said shaft, a gear carried by said second element` a pinion movable into and .out of engagement with said gear, and hand actuated means for causing said pinion and ear to engage and for rotating said pinion or adjusting said second element circumferentially relatively to said firstelement.

4. In. an adjusting device for cylinder elements the combinatlon of a rotatable shaft, a cylinder element fixed thereto, a second cylinder element loosely mounted on said s aft, a gear carried by said second element. a pinion movable into and out of engagement with said gear, spring ,means for normally holding said pinion out of engagement with said gear, and` hand actuated means for causing said pinion and gear to .engage and for rotating said pinion for adjusting said second element circumferentially relatively to said first element.

5; In an adjusting device for cylinder elements the combination of a rotatable shaft a cylinder element fixed thereto, 'a second cylinder element loosely mounted' on said shaft, means for clamping said second element to said shaft, a bevel gear carried by said second element, a shaft disposed at an angle to said rotatable shaft and mounted for rotation and for endwise movement, a bevel pinion fixed to said angularly disposed shaft and adapted for engagement with said bevel gear` and hand actuated means for moving said angularly disposed shaft end- Wise for causing said pinion to engage said bevel gear and for rotating said pinion While in engagement with said bevel gear for adjusting said second element circumferentially relatively to said first element.

G. In an adjusting device for cylinder elements the combination of a rotatable shaft, a cylinder element fixed thereto, a second cylinder element loosely mounted on said shaft, means for clamping said second elementto said shaft, a bevel gear carried by said second element, a shaftdisposed at an angle to said rotatable shaft and mounted for rotation and for endwise movement, a bevel pinion fixed tosaid angularly disposed shaft and adapted for engagement with said bevel gear, spring means for normally holding said pinion out of engagement Withsaid gear, and hand actuated means for moving said angularly disposed shaft endwise for causing said pinion to engage said bevel gear and for rotating said pinion while in engagement with said bevel gear for adjusting saidse-cond'element circumferentially relatively to said first element.

In witness whereof. I hereby affix my signature this 17 day of June, 1920.
